Moritz Zimmermann, an awkward and ambitious high schooler in the fictional German town of Rinseln, is dumped by his long-time girlfriend, Lisa Novak, after she returns from a transformative exchange year in the United States. Eager to win her back and prove he is not a loser, Moritz learns that Lisa has fallen for Dan Riffert, a popular jock and the school's primary drug dealer. Desperate to regain her affection and status, Moritz impulsively boasts that he can acquire a superior batch of Dutch MDMA much cheaper than Dan’s current supplier.To make good on this absurd claim, Moritz enlists his best friend, Lenny Sander, a wheelchair-bound tech genius suffering from a terminal degenerative illness. Utilizing Lenny’s darknet expertise, they successfully buy a large quantity of high-grade narcotics from a pair of volatile, psychopathic Dutch brothers, Buba and Goodtimz. However, Lisa does not take Moritz back, leaving him stranded with thousands of euros worth of illegal drugs and no way to offload them safely.Faced with mounting danger and financial ruin, Moritz pivots. Instead of a local street operation, he leverages his coding skills to launch "MyDrugs," a sleek, consumer-friendly online webshop modeled after legitimate e-commerce platforms like Amazon. The site becomes an overnight viral sensation on the darknet, offering fast shipping, customer reviews, and reliable quality. To manage the booming enterprise, Moritz and Lenny recruit high school acquaintance Dan, whose physical presence helps handle local logistics.As the business scales explosively, the trio’s lives spiral
out of control. Moritz becomes intoxicated by power and wealth, alienating Lenny and Dan, and obsessively tracking Lisa. Internal conflicts escalate when the volatile supplier Buba demands a larger cut, leading to a violent confrontation where Buba is accidentally killed. Moritz, Lenny, and Dan are forced to bury the body, dragging them deeper into a world of genuine criminality.Simultaneously, law enforcement closes in, led by an obsessive investigator. Lenny falls in love with a mysterious coder known as "Kira," who turns out to be an undercover cybercrime investigator. Meanwhile, Moritz’s clueless father, Seba, a local
police officer, inadvertently investigates his son’s own company. The pressure mounts as the Dutch cartel seeks revenge for Buba’s disappearance, threatening the boys' families. In the climactic showdown, the teenagers must outsmart both international gangsters and the federal police. Although they narrowly escape prison and survive the cartel war, the immense wealth and global reach of MyDrugs ultimately destroy their friendship, leaving Moritz isolated, wealthy, and fundamentally changed as he faces the staggering consequences of his digital empire.
